SuperCOSMOS

Submitted by Kevin Jardine on 25 May, 2006 - 09:26

I've discovered the SuperCOSMOS sky survey. For southern hemisphere objects, this provides a higher resolution than DSS-2, plus blue and hydrogen-alpha plates. As a result, I can create much better nebula images and I'm in the process of redoing many of the images on this site to take advantage of this new data. There are several hundred images to do, so this will take a while.

My goal is to create a full set of descriptions and colour images for all the nebulae in the Sharpless and RCW catalogs. So far as I know, this is the first time this has been done and I hope that it will be a useful reference.

Site reorganised

I've moved most of the text from the front page at http://galaxymap.org to the introduction to the book. There is now a much simplified front page with a random beautiful nebula image.

Since my last blog entry, I've added a RCW catalog gallery to complement the Sharpless catalog gallery. As the DSS-2 blue plates are missing for much of the southern hemisphere, I've just used the red and infrared (green) plates to construct many of the RCW images. This results in a lot of pink/purple nebulae, but is better than no images at all.

I've also added a simpler and more accurate "fantasy" map. The regions shown on this map will become the basis for much of the Our Galactic Region book.
